Abstract

Câble de fibres optiques comprenant une âme composée essentiellement d'une ou plusieurs fibres optiques droites et parallèles, et d'une gaine protectrice qui entoure l'âme. Ce câble est réalisé par passage d'un faisceau 27 de fibres optiques dans le canal central d'un pointeau 12 d'une tête d'extrusion. Des fils 24 d'armature en acier sont avancés en même temps que les fibres 27 dans d'autres canaux du pointeau 12. Une matière plastique devant former la gaine 25 du câble est extrudée par une filière 11 sur le faisceau 27 de fibres optiques, de manière à enrober les fils métalliques 24 de renfort et à permettre aux fibres optiques de pouvoir se déplacer peu près librement à l'intérieur de cette gaine. Domaine d'application: fabrication de câbles de fibres optiques.Optical fiber cable comprising a core composed essentially of one or more straight and parallel optical fibers, and a protective sheath which surrounds the core. This cable is produced by passing a bundle 27 of optical fibers through the central channel of a needle 12 of an extrusion head. Steel reinforcing wires 24 are fed along with the fibers 27 into other channels of the needle 12. A plastic material to form the sheath 25 of the cable is extruded through a die 11 onto the bundle 27 of optical fibers, so as to coat the reinforcing metal wires 24 and to allow the optical fibers to be able to move more or less freely inside this sheath. Field of application: manufacture of optical fiber cables.
